A crane is an essential piece of equipment in factories, warehouses and assembly lines. They come in a variety of sizes and types, from the large to a small bench based lifting system.
A gantry crane is a crane built on a structure or gantry. It is built “over” or straddles a work area. There are a variety of gantry cranes available.
Types of Gantry Cranes Available
Light Capacity Track Cranes – Aluminum
This type of gantry crane is especially suited to large work areas. It is essentially an aluminum frame structure that can be fixed to any existing steel or other structures in the ceiling of any workspace. This particular type of gantry crane is suitable for use in large spaces. It consists of two parallel, tracks or “runways” with a “cross beam or bridge”. On this cross beam, lifting equipment, such as hoists or “vacuum lifters” can be attached. It can be used in pretty much all production areas for assembly and processing. Rollers are used on the tracks. This makes for a smooth movement, helps prevent tilting, and results in very low friction. Loads up to 3Kg/m can be moved. This also has the added advantage that items can be moved quickly and accurately.
Light Capacity Track Cranes – Steel
Another possibility is to use a variety of steel based gantry cranes. These include:
A Free Standing Track Crane
It has two beam structures supporting two run ways and a bridge. This structure allows for flexibility as this structure can easily be extended.
Ceiling Supported Track Crane
In this case, the structure is supported by “droppers” from the ceiling thus freeing up space around the structure.
Cantilevered Track Crane
In this case, the structure uses a system of posts and cross beams to secure the gantry crane to a supporting wall.
These various types of track cranes have a wide lifting capacity from 45Kg to 1000Kg. Bridges range in length from 2 metres to 8 metres, and are incremented in half metre lengths. Runways are available in multiples ranging from 3 metres to 8 metres.
These can vary in size but the ones that are being focused on here are for more localized use in production and assembly lines. These are a type of crane that Jib cranes Australia has available. These Jib or Slewing cranes use an arm that can be moved into position for lifting. These particular jib cranes are very versatile. Weights as high as 990Kg can be lifted and moved. They are very easy to move and are ergonomically designed. This makes these cranes very safe to use. They can use a variety of lifting devices including chain and cable hoists, cable “balancers” or vacuum lifting devices.
A workstation crane can be defined as a crane allocated to a specific work area or work station on say an assembly line. There would be a need for a localized crane to assist in probably repetitive routines.
These are best used with a “jumbo flex” vacuum lifter. A large variety of previously awkward loads, such as moving sacks, becomes a one man operation. See more Millsom Materials Handling!
Therefore, different cranes for sale have the correct crane and lifting systems which will speed up any operation. Thus, they add to the safety and efficiency of a workplace.
